What is persistent genital arousal disorder?

The condition typically affects women, and can lead to ongoing physical pain, stress, and psychological problems as it interferes with daily life.

Common symptoms of PGAD include:

pressure

burning

pounding

wetness

pins and needles

itching

The condition can leave some sufferers feeling as though they are about to experience an orgasm, without ever reaching climax.

While others will endure waves of spontaneous orgasms.

Now, with the expertise of researchers at Michigan University, Amanda is being offered some hope.

Dr Priyanka Gupta, assistant professor of neurology, said: “Because it’s such a rare diagnosis and there’s been such little research we don’t know exactly what causes it. We suspect it’s multifactorial.

“I don’t have a quick cure for this but we’re going to be trying a few different therapies. I’m very hopeful that we can get her functioning better.”

Amanda also now has the support of her fiancé JoJo, whom she met a year ago.
